Build a Voicemail Generator with ElevenLabs API

Description and use

Automated voicemail generator using ElevenLabs TTS to produce MP3 files from templated text with dynamic variables.

Problem

Manually recording voicemails for demos or campaigns is tedious, especially when multiple languages or consistent brand voice are needed.

Outcome

The workflow produces a ready‑to‑use MP3 voicemail that matches the brand voice and can be generated programmatically for any recipient.

Workflow

• Obtain ElevenLabs API key via affiliate signup
• Install Python dependencies (requests, pydub, ffmpeg)
• Create a text template with placeholders
• Fill template with runtime data
• Call ElevenLabs text‑to‑speech endpoint to synthesize audio
• Convert raw audio bytes to AudioSegment
• Apply optional fade‑in/out
• Export final MP3 file
• Upload to phone system

Evidence

With modern text‑to‑speech (TTS) services, you can generate high‑quality audio on the fly.
